The article discusses the benefits of L3s, which are applications with different requirements such as privacy, performance, and centralization vs decentralization. The first layer is slow and congested because each verification program needs to recompute and verify transactions. The second layer is faster as a single sequencer generates blocks and others only need to verify their validity. The article mentions Stark ex as a typical L2 use case for optimizing apps. AllStar uses language to express these statements and gathers evidence to verify the correctness of L2 transactions.

L3 World#

Gideon Kaempfer, the StarkWare Core Engineering Head, talks about the benefits of L3s.
Various applications define their own different requirements, such as privacy, performance, and centralization vs. decentralization.
In the layered architecture, the first layer is public, decentralized, and secure, but it is slow because each validator needs to recompute and verify transactions, leading to congestion issues.
The second layer is faster because a single sequencer generates blocks and others only need to verify the validity of these blocks.
By re-invoking, it is possible to prove the execution of programs and send proofs to the first layer.
Stark ex is a typical App optimizing L2 use cases.
By using language to express those statements, AllStar will aggregate all the evidence to verify that L2 transactions are correct.
